trait MetricsProviderForScenario extends AnyRef
Abstraction for metrics frameworks used by different scenario engines (e.g. Flink metrics and Dropwizard). Metrics instances created/registered by this trait represent metric for particular scenario and task instance (e.g. particular slot for Flink). Method calls are *not* idempotent at the moment, so it's callers responsibility to call them only once for one metric during lifecycle (e.g. during open in Lifecycle)
